The SN74ALVCH16244 is designed specifically  
to improve the performance and density of 3-state  
memory address drivers, clock drivers, and  
bus-oriented receivers and transmitters.  
The device can be used as four 4-bit buffers, two  
8-bit buffers, or one 16-bit buffer. It provides true  
outputs  
and  
symmetrical  
active-low  
output-enable (OE) inputs.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN74ALVCH16244 is characterized for operation from –40°C to 85°C.
